Here's the steps to what I'm doing. First, I create a new visual class,
throw a JMenuBar on the ContentPane, then a JMenu on the JMenuBar, and
finally drag a JMenuItem on the JMenu.

Then I set the text for the JMenu (File) and JMenuItem (Open). The
problem is from within the IDE, I never see the Open menu item visually;
it only appears at runtime. What if I want to make a sub menu, do I have
to do that by hand from within code? Or is there a setting or
configuration item which I am missing?
